As indicated in the title.
I downloaded the SDK and started the SDK Manager. The first window popped up indicating a need to login to my developer account. Pressed "Login", second window popped up a "Sign In" window with a "Create One" link. Selected Create One, entered the info and selected Create Account. Window goes to a single spinning gear...forever. Start over, says account exists. Try to login, now back to spinning gear. Login never completes.
Any help?
Note this is on Windows 10.
Another note - retrying login with a bad password brings up an error box. But login with correct info still doesn't complete.
